摘　　要：记述四瘤蚱属1新种:狭顶四瘤蚱Tetradinodula strictivertex Mao&Li sp.nov.,提供了特征照片图。新种与网纹四瘤蚱T.reticulata Mao&Li,2020相似,但以下面的特征区别于后者:头顶宽为一眼宽的1.7倍(后者为2.9倍);头顶与复眼上缘在同一水平面(后者头顶明显超过复眼上缘);触角中段部分长约为宽的5.2倍(后者为3.1倍);侧单眼位于复眼内缘中部稍下处(后者侧单眼在复眼下缘稍上方处);前胸背板外侧隆线近平直(后者外侧隆线在前部强烈弯曲)。One new species in the genus Tetradinodula Zha,2017 is described and illustrated with photographs.Tetradinodula strictivertex Mao Li sp.nov.is similar to T.reticulata Mao Li,2020,but differs from the latter in:1)vertex 1.7 times as wide as one eye(2.9 times in T.reticulata);2)vertex nearly at the same level of upper margin of eyes(vertex markedly surpassing the upper margin of eyes in T.reticulata);3)antenna with middle segments about 5.2 times as long as wide(3.1 times in T.reticulata);4)lateral ocellus situated slightly below the middle of inner margin of eye(lateral ocellus placed slightly above lower margin of eyes in T.reticulata);and 5)external lateral carina of pronotum nearly straight(external lateral carina strongly curved in T.reticulata).
